The Status of the World's Land and Marine Mammals: Diversity, Threat, and Knowledge
Knowledge of mammalian diversity is still surprisingly disparate, both regionally and taxonomically. Here, we present a comprehensive assessment of the conservation status and distribution of theExpand

SEABIRD COMMUNITY STRUCTURE ALONG A PRODUCTIVITY GRADIENT: IMPORTANCE OF COMPETITION AND ENERGETIC CONSTRAINT
The oceanic eastern tropical Pacific supports a speciose seabird community that feeds in flocks and depends for food on schools of tunas and dolphins, which force prey to the surface. We analyzedExpand

Blue whale habitat and prey in the California Channel Islands
Abstract Whale Habitat and Prey Studies were conducted off southern California during August 1995 (WHAPS95) and July 1996 (WHAPS96) to (1) study the distribution and activities of blue whales andExpand

RATES OF INCREASE IN DOLPHIN POPULATION SIZE
ABSTRACf Annual finite rates of increase in dolphin population size were estimated to vary up to a maximum of 1.09, using simulation, based on ranges in vital rates. Vital rate ranges were definedExpand

BLUE WHALE (BALAENOPTERA MUSCULUS)DISTRIBUTION IN THE EASTERN TROPICAL PACIFIC
The distribution of blue whales, Balaenoptera musculus, in the eastern tropical Pacific (ETP) was analyzed from 211 sightings of 355 whales recorded during research vessel sighting surveys or byExpand

GRAY WHALE CALF PRODUCTION 1994–2000: ARE OBSERVED FLUCTUATIONS RELATED TO CHANGES IN SEASONAL ICE COVER?
We conducted shore-based sighting surveys to estimate the number of northbound migrating gray whale calves passing Piedras Blancas, California, for seven consecutive years (1994-2000). In addition,Expand

Physical forcing and the dynamics of the pelagic ecosystem in the eastern tropical Pacific: simulations with ENSO-scale and global-warming climate drivers
We used a model of the pelagic ecosystem in the eastern tropical Pacific Ocean to explore how climate variation at El Nino – Southern Oscillation (ENSO) scales might affect animals at middle andExpand

Spatial models of delphinid (family Delphinidae) encounter rate and group size in the eastern tropical Pacific Ocean
We use temporally dynamic environmental variables and fixed geographic variables to construct generalized additive models to predict delphinid (family Delphinidae) encounter rates (number of groupsExpand
